Can the Apple M4 Max 64GB run SRU++ Large?
Yes — here's how fast and up to what context, with real measured numbers.
SRU++ Large on the Apple M4 Max 64GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 849k | 793.3-956.7 t/s | ~14.5-17.5 (slow) |
| Q8 | yes | 852k | 1586.7-1913.3 t/s | ~29.1-35 (slow) |
| Q4 | yes | 854k | 2833.3-3416.7 t/s | ~51.9-62.6 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
FAQ
Can the Apple M4 Max 64GB run SRU++ Large?▶
Yes. At Q4 it generates ~2833.3-3416.7 tok/s and fits up to 854k context; beyond that it spills to SSD swap and slows to ~51.9-62.6 tok/s.
How much context fits?▶
At Q4, up to about 854k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
